FIELD OF THE INVENTION

The field of the invention is distributed storage systems and methods.

BACKGROUND

The following description includes information that may be useful inunderstanding the present invention. It is not an admission that any ofthe information provided herein is prior art or relevant to thepresently claimed invention, or that any publication specifically orimplicitly referenced is prior art.

Mobile devices provide many conveniences to people nowadays due to theirportability. As these mobile devices are getting more powerful, morefeatures and functionalities from these devices are demanded. Oftentimes, large data sets are needed to support some of these features andfunctionalities (e.g., object-recognition data set, digital media suchas videos, audios, documents, augmented reality content, etc.). It isnot realistic or optimal to permanently store the entire data sets forall the features and functionalities that might be activated from timeto time, especially when the storage space in these mobile devices arecomparatively small. It has been contemplated by others to have theselarge data sets to be stored remotely (e.g., in the cloud), and have themobile devices to retrieve these data sets on demand. Thus, the datasets are reside remotely, and only when certain related functionalitiesare activated the data sets be retrieved by the mobile devices. Onedisadvantage of this solution is the latency to gain access to thefunctionalities created by retrieving these datasets. Due to the size ofthese datasets and the limited bandwidth of these mobile devices, it maytake minutes or hours to download the entire datasets required bycertain functionalities.

Effort has been made in developing systems and methods of managing theaccess of data content among portable storage devices on a network. Forexample, U.S. Pat. No. 7,743,213 to Hong titled “Portable Storage Devicewith Network Function,” issued Jun. 22, 2010, discusses an electronicapparatus coupled to a plurality of portable storage devices andmanaging the access of content between the memory unit of each portablestorage device and a remote network host. Murphy, however, does notteach managing the activation or deactivation of the content distributedamong the portable storage devices. U.S. patent application 2010/0205148to Leblanc et al. titled “Method and System for Pushing Content toMobile Devices,” published Aug. 12, 2010, discusses the pushing ofcontent to a plurality of mobile devices such that the content is storedlocally on the device and available for offline viewing. Unfortunately,LeBlanc also fails to provide insight into methods of activating ordeactivating the stored content online or offline, locally or otherwise.

U.S. Patent Publication 2013/0227052 entitled “Image Content BasedPrediction and Image Cache Controller” to Wenzel et al., filed Oct. 27,2011, discloses a caching controller that predicts multiple views ofimages that a user would view in the near future based on the currentview of images, and pre-loading those multiple view of images on thedevice. A non-patent literature entitled “Detection Caching for FasterObject Detection” by Pham et al., published in 2005, discloses a methodof pre-loading certain face detection parameters that were previouslycomputed based on similarity between the current image and a previousimage.

Other efforts made in the area of improving the speed of applicationbased on caching include U.S. Patent Publication 2012/0099533 entitled“Content Caching in the Radio Access Network (RAN)” to Kovvali et al.,filed Dec. 29, 2011, U.S. Patent Publication 2012/0243732 entitled“Adaptable Framework for Cloud Assisted Augmented Reality” toSwaminathan et al., filed Sep. 19, 2011, and International ApplicationWO 2012/177194 entitled “Caching Support for Visual Search and AugmentedReality in Mobile Networks” to Damola, filed Jun. 21, 2011.

Even though the above references are useful when data for only onespecific purpose application is being dealt with, they do not addresscircumstances that are unique to mobile devices, which is when manydifferent applications can be activated in different situations. Thus,there is still a need for a distributed storage system in which datacontent and associated activation criteria are disseminated across thereadable memory of a plurality of mobile devices via a mobile deviceinterface.

DETAILED DESCRIPTION

Throughout the following discussion, numerous references will be maderegarding servers, services, interfaces, engines, modules, clients,peers, portals, platforms, or other systems formed from computingdevices. It should be appreciated that the use of such terms is deemedto represent one or more computing devices having at least one processor(e.g., ASIC, FPGA, DSP, x86, ARM, ColdFire, GPU, multi-core processors,etc.) configured to execute software instructions stored on a computerreadable tangible, non-transitory medium (e.g., hard drive, solid statedrive, RAM, flash, ROM, etc.). For example, a server can include one ormore computers operating as a web server, database server, or other typeof computer server in a manner to fulfill described roles,responsibilities, or functions. One should further appreciate thedisclosed computer-based algorithms, processes, methods, or other typesof instruction sets can be embodied as a computer program productcomprising a non-transitory, tangible computer readable media storingthe instructions that cause a processor to execute the disclosed steps.The various servers, systems, databases, or interfaces can exchange datausing standardized protocols or algorithms, possibly based on HTTP,HTTPS, AES, public-private key exchanges, web service APIs, knownfinancial transaction protocols, or other electronic informationexchanging methods. Data exchanges can be conducted over apacket-switched network, the Internet, LAN, WAN, VPN, or other type ofpacket switched network.

The following discussion provides many example embodiments of theinventive subject matter. Although each embodiment represents a singlecombination of inventive elements, the inventive subject matter isconsidered to include all possible combinations of the disclosedelements. Thus if one embodiment comprises elements A, B, and C, and asecond embodiment comprises elements B and D, then the inventive subjectmatter is also considered to include other remaining combinations of A,B, C, or D, even if not explicitly disclosed.

As used herein, and unless the context dictates otherwise, the term“coupled to” is intended to include both direct coupling (in which twoelements that are coupled to each other contact each other) and indirectcoupling (in which at least one additional element is located betweenthe two elements). Therefore, the terms “coupled to” and “coupled with”are used synonymously.

The inventive subject matter provides apparatus, systems, and methods ofpre-loading (or caching) content to several mobile devices for futureuse by at least one of the mobile devices. In some embodiments, themobile devices are communicatively coupled with each other to form anetwork, such as a personal network, or a peer-to-peer network. Thus,the pre-loaded content can be used by applications executed in any oneof the mobile devices within the network.

A personal area network can include portable disparate devices that auser would carry and use, the devices can include smart phones, smartwatches, smart glasses, music players, portable game consoles, etc.These devices often can use short-range wired or wireless communicationinterface to communicate with each other (e.g., Bluetooth®, wifi, etc.).

FIG. 1 illustrates an example content storage system 100 of someembodiments. The storage system 100 includes a content server 105, acontent database 115, and several mobile devices 125 that are coupledwith each other over a network 120 via a mobile device interface. Asshown, the mobile devices that are connected with each other in thestorage system 100 can include different types of mobile devices.Examples of mobile devices include a mobile phone, a laptop, a tablet, aportable game console, an e-book reader, an electronic pen, a set topbox, medical device, or any other portable computing devices. Inaddition, the mobile devices can also include a vehicle such as anautomobile, an aircraft, a spacecraft, a boat, a ship, a submersible, abus, a train, or a truck. Each mobile device comprises a processor forexecuting a set of instructions and a storage area for storing contentthat will be used by software applications executed in the mobiledevice.

The mobile devices can be coupled with each other in many ways. In someembodiments, the mobile devices can be coupled with each other via awired interface, such as an Ethernet interface, an optic fiberinterface, an asynchronous transfer mode interface, or even a publicswitched telephone network. In other embodiments, the mobile devices canbe coupled with each other via a wireless interface, such as an Wi-Fiinterface, WiGIG interface, a celluar interface, a mesh networkinterface, a WiMAX interface, WiGIG, a microwave interface, anUltra-wideband interface, a wireless HD interface, a wireless personalarea network, a wireless home digital interface, a wireless USBinterface, or ZigBee interface.

In some embodiments, the content server 105 can be implemented in one ofthe mobile devices or distributed across more than one mobile device. Inother embodiments, the content server 105 can be implemented at a devicephysically separated from the mobile devices, and communicativelycoupled with the mobile devices through a network (e.g., the Internet, apeer-to-peer network, a local area network, etc.).

As shown in FIG. 1, the content server 105 is communicatively coupledwith the content database 115. In some embodiments, the content databaseis configured to store content for software applications that can beexecuted by at least one of the mobile devices. Preferably, the contentthat is stored in the content database is sufficiently large such thatit is impossible or impractical to store the content locally at themobile devices. In some embodiments, the content that is being stored inthe content database is activatable, meaning that the each portion ofthe content can be activated to be used by a software application.Examples of activatable content that is stored in the content database115 include object recognition data for an object recognitionapplication, audio data for an audio player, video data for a videoplayer, image data for an image viewing application, text data for atext reading application, map and traffic data for a navigationapplication, kinesthetic data, application data, telematics data,functionality data, medical data, patient data, or business data for abusiness recommendation engine.

The content server 105 of some embodiments is configured to cause atleast one of the mobile devices to retrieve (e.g., download) contentassociated with a software application and store the content locally inthe storage area of the at least one mobile device before instructionsfor activating the content is received.

FIG. 2 illustrates the storage system 100 in more detail. As shown inthe figure, the content server 105 includes a content manager 215, adatabase interface 220 configured to communicate with the contentdatabase 115, a device interface 110 configured to communicate with themobile devices 125 a and 125 b, rules database 220 storing sets ofmulti-conditional content activation criteria for different contentstored in the content database 115. The content server 105 can befurther configured to exchange content with the mobile devices 125 a and125 b via a content exchange protocol. The content exchange protocolcould include at least one of a universal plug-in-play protocol, aDigital Living Network Alliance (DLNA) framework, a media transportprotocol, or a high definition multi-media interface protocol.

In some embodiments, the mobile device 125 a is identical to the mobiledevice 125 b. In other embodiments, mobile devices 125 a and 125 b aredifferent devices, and are communicatively coupled with each other via aconnection or network. In some embodiments, the content database isphysically located at a remote location with respect to the mobiledevices and/or the content server 105.

Mobile devices 125 a and 125 b can be the same mobile device ordifferent mobile devices that are connected with each other over anetwork as stated above (e.g., personal network, peer-2-peer network,etc.). Each mobile device 125 a and 125 b also includes a storage area(such as storage area 205 for mobile device 125 a and storage area 210for mobile device 125 b) for storing data for use by softwareapplications that can be executed in the mobile devices 125 a and 125 b.Preferably, each of the storage areas 205 and 210 has storage capacitythat is smaller than the capacity of the content database 115. Thus, itis conceived that most or all of the content data that can be used bythe mobile devices' software applications is permanently stored in thecontent database 115.

The storage areas 205 and 210 on each mobile devices 125 a and 125 b canbe at least partially under control of the content server 105 and can beconfigured to restrict access to any content under command of thecontent server 105. Alternatively, the storage areas 205 and 210 cancomprise a demarcated secured portion that is secured under the commandof the content server. In even further alternative embodiments, thestorage areas 205 and 210 can compose a virtual machine that is at leastpartially under control of the content server 105. In such embodiments,the interaction between the mobile devices 125 a/ 125 b and the contentdatabase 115 can occur within the virtual machine under command of thecontent server 105.

As mentioned above, each content that is stored in the content database115 can be activated for use by a particular software application. Insome embodiments, the content can be activated upon a mobile devicedetecting an activation event (e.g., a user input such as a click, agesture, a sound, or a command via the user interface of the mobiledevice, a detection of sensor data, a change of sensor data, and imagecapture, a point-of-use, a payment, a rating, a vote, and a contextetc.). However, since the content can be large in size and is usuallystored in the content database that is remote from the mobile devices125 a and 125 b, the content needs to be transmitted from the contentdatabase 115 to at least one of the mobile devices 125 a and 125 bbefore the content can be used by the software application. Due tobandwidth limitations and network traffic, it is conceived thattransmitting the desired data upon detecting the activation event cancause substantial and undesirable latency to using the application.Thus, it is conceived that the storage system 100 can cause some or evenall of the data to be transmitted to the storage area of at least one ofthe mobile devices 125 a and 125 b before the activation event isdetected.

In some embodiments, the content server 105 uses the sets ofmulti-conditional content activation criteria to determine which contentto be transmitted to the mobile devices 125 a and 125 b at which pointin time before the activation events of the content are detected.Specifically, the multi-conditional content activation criteriaindicates what condition(s) needs to be met before beginning to transmitcontent data from the content database 115 to the mobile devices 125 aand 125 b. One should appreciate that the multi-conditional contentactivation criteria servers multiple, simultaneous functions. First, thecriteria has rules and conditions that govern caching or storage of theactivatable content as inactive content. Second, the complete criteriaindicate when the inactive content becomes activated. Thus, the systemhas a single set of rules.

The conditions can depend on different types of factors, such as sensordata from the mobile devices (e.g., location tracking data, temperature,image data captured by an optical sensor on the device, time data,detection of an external device, etc.), payment data, user interactionwith at least one of the mobile devices, issuance of a payment, a userinteraction with the mobile device, the context of the mobile device, orthe recognition of a digital representation of an object as a targetobject. The digital representation of an object can represent at leastone of a sound, a symbol, a two dimensional object, a three dimensionalobject, a movement, an image, a magazine, a newspaper, a display screen,a toy or a vehicle.

The multi-conditional content activation criteria for each part of thecontent can also include a combination of these different types offactors. For example, the content server 105 can determine to begintransmitting content related to a specific application to the mobiledevices 125 a and 125 b when several types of sensor data in combinationwith the user interaction data meets the criteria specified in themulti-conditional content activation criteria for the content.

Instead of transmitting a complete set of content for a specificapplication all at once upon the satisfaction of the entiremulti-conditional content activation criteria for the content, thecontent server 105 of some embodiments can be configured toprogressively transmit different portions of the content when differentsubset of the conditions within the multi-conditional content activationcriteria for the content are satisfied.

For example, when the multi-conditional content activation criteria fora set of content includes five conditions (Condition ‘A’, Condition ‘B’,Condition ‘C’, Condition ‘D’, and Condition ‘E’) and associated cachingrules, the content server 105 can be configured to transmit portions ofthe content according to this example set of rules: begin transmittingone third of the content to the mobile devices when two of theconditions are satisfied, begin transmitting another one third of thecontent to the mobile devices when another two of the conditions aresatisfied, and then transmitting the remaining content when the finalcondition is also satisfied. In some embodiments, this set of rules canalso specify which conditions (e.g., Condition ‘A’ and Condition ‘C’)should be satisfied for which portion of the content (e.g., which files)to be transmitted. One benefit of this progressive transmission is tospread out the network traffic and to allow more time for the entire setof content to be transmitted. Contemplated rules governing storage orcaching of the content can operate as a function of the conditions,nature of the content, rights management, or other factors.

Instead of transmitting the portions of the content immediately afterdetecting the satisfaction of one or more conditions, the content server105 can also be configured to transmit the portion of the content duringa particular time period (e.g., off-peak hours) or according to a feeschedule.

In addition to being progressive, the content server 105 can also beconfigured to be regressive in transmitting content to the mobiledevices 125 a and 125 b. Specifically, once the content server 105 hastransmitted a portion of the content to the mobile devices because asubset of conditions from the multi-conditional content activationcriteria are satisfied, the content server 105 can also be configured tocause the mobile devices to remove the portion of the content (i.e.,discard, free up or even overwrite memory that is used to store theportion of the content) when at least one condition from the subset ofconditions is no longer satisfied. This regressive feature allows themobile devices to free up memory space when it is no longer needed andallows for better security in the content as the content will not bestored in the mobile device when it is not needed.

Thus, the content server 105 would continuously transmit portions of thecontent to the mobile devices 125 a and 125 b as the more conditionswithin the multi-conditional content activation criteria are satisfied.In some embodiments, the content server also removes portions of thecontent from the mobile devices 125 a and 125 b when some of theconditions from the multi-conditional content activation criteria havechanged from satisfied to dissatisfied. As all conditions within themulti-conditional content activation criteria have been satisfied, thecontent server 105 should cause the entire content for the applicationto be transmitted to the mobile devices 125 a and 125 b.

Preferably, the entire content for the application is transmitted to themobile devices 125 a and 125 b before any content activation event isdetected. Upon detecting the content activation event when allconditions are satisfied, and the complete transmission of the entirecontent for the application, the mobile device 125 a or 125 b isconfigured to activate the content. In some embodiments, the contentserver 105 or mobile devices can activate the content on the mobiledevices 125 a and 125 b by at least one of several possible techniques.Content can be activated by unlocking the content, decoding the content,revealing the content, extracting the content, decompressing thecontent, rendering and presenting the content, expanding the content,delivering the content, translating the content, converting the content,authorizing access, indexing the content, configuring the mobile devicesand/or the content server 105 using the content, modifying the content,authenticating a user, moving the content to a non-content servercontrolled memory, or any other means of making the content usable.

Once the content is activated, the content server 101 can enable themobile devices 104 to interact with their respective stored content. Theinteraction could be at least one of a presentation of the content, anexecution of the content, a transmission of the content, a deletion ofthe content, a management of the content, an indexing of the content, aconfiguration based on the content, a transaction related to thecontent, and a modification of the content.

In the storage system 100, content that has been transmitted and storedin one mobile device within the network of mobile devices can beused/activated by another mobile device within the network. Thus,content that is stored in mobile device 125 a can be used by anapplication running on mobile device 125 b. In addition, the storagesystem 100 can further comprise a distributed storage area networkcomprising storage areas of at least some of the mobile devices. Thedistributed storage area network comprises an optic fiber backbone, meshnetwork backbone, an ad hoc network backbone, a personal area networkbackbone, or other type of network. In these embodiments, the contentserver 105 is also configured to manage content stored in the distributestorage area network.

Further, the distributed storage area network can be independentlypowered and can be powered, at least in part, by gasoline. The datadensity of the distributed storage area network can be at least oneTerabyte per 100 m². The storage areas of the distributed storage areacan move relative to one another. In total, the storage area cancomprise one gigabyte of storage capacity or more. Such an approach inembodiments where the mobile devices comprise vehicles and each vehiclehas a storage area (e.g., local hard drive, local solid state drive,etc.). Thus, a highway filled with cars can operate as a distributedstorage facility for all car on the highway or for edge devices near thehighway.

One use of such a distributed storage area network could be todistribute large data content sets across moving devices such asvehicles or apparel. With the costs of readable memory continuing tofall, data can be stored at low cost and in minimal dimensions on anexpanding list of everyday devices and items, including devices nottypically associated with data storage. By distributing data across suchdevices, particularly those that are portable, a distributed storagenetwork could benefit from several advantageous technical effects suchas improved data transfer across local or short-ranged networkingprotocols, improved access during periods of lost network connectivity,improved data encryption or user anonymity, or potential reductions inthe cost of storing data content.

FIGS. 3-5 further illustrates the operations of the storage system 100by way of different real-world examples. Specifically, FIG. 3illustrates an example of using the storage device to pre-load (cache)content data via three stages (stage 305, stage 310, and stage 315) ofthe figure. As shown in FIG. 3, mobile device 125 is communicativelycoupled with content server 105 and content database 115. In thisexample, the content database 115 stores, among other things, eightaudio files for a music player within the mobile device 125. The eightaudio files are activatable content as the music player can activate theaudio files by decoding and playing the files. The content server 105also includes a rules database 220 (not shown) that includesmulti-conditional content activation criteria for content (e.g., theeight audio files) related to the music player.

The multi-conditional content activation criteria include the followingthree conditions: (1) location is the study room; (2) John is in thestudy room; (3) Mary is in the study room; and (4) law school readingmaterials are in the study room. In addition to the conditions, themulti-conditional content activation criteria also specifies thefollowing data transmission rules: (a) transmit one fourth of thecontent (e.g., the first two files of the eight audio files) when one ofthe four conditions is satisfied; (b) transmit another one fourth of thecontent (e.g., the next two files of the eight audio files) when two ofthe four conditions are satisfied; (c) transmit another one fourth ofthe content (e.g., the next two files of the eight audio files) whenthree of the four conditions are satisfied; and (d) transmit theremaining of the content (e.g., the last two files of the eight audiofiles) when all four conditions are satisfied. Preferably, mobile device125 includes a location sensor and object recognition sensor that isconfigured to recognize both John and Mary (through image recognition,audio recognition, etc.).

In stage 305, the content server 105 has detected that the mobile deviceis located within the study room and that John is also in the study room(e.g., based on facial recognition data). In this example, the locationof the mobile device can be detected in many ways. In some embodiments,the mobile device can store the location coordinate of the study room,and can include a location tracking sensor (e.g., a GPS module) thatcommunicates with the satellites to determine whether the location ofthe mobile device coincide the location of the study room. In otherembodiments, the mobile device can communicate with external devices(e.g., RFID chips) located in proximity of or within the study room todetermine the location of the mobile device with respect to the studyroom.

Similarly, the mobile device can detect the presence of John in thestudy room in many ways. In some embodiments, the mobile device caninclude an optic sensor and a facial recognition module. The mobiledevice first allows the user to capture a digital representation of thestudy room that includes any objects located within the room, the mobiledevice then uses the facial recognition module to determine if there isany person located within the room, and whether the person's facialfeatures coincide with that of John. In other embodiments, the mobiledevice can use the voice (or any other detectable and distinctivefeatures) of people in the room to determine whether John is present inthe room.

Upon detecting that these two conditions are met, the content server 105instructs the mobile device 125 to receive the first four audio filesfrom the content database 115, as two of the four conditions within themulti-conditional content activation criteria are satisfied.

In stage 310, the content server 105 has detected that Mary and lawschool reading materials are also in the study room along with John.Accordingly, the content server 105 instructs the mobile device 125 toreceive the last four audio files from the content database 115, as allfour conditions within the multi-conditional content activation criteriaare satisfied. At this point, all eight audio files that are related tothe audio player have been transmitted to the mobile device 125. Theyare stored in a storage area of the mobile device 125, but are notactivated yet as the content activation event has not been detected. Inthis example, the content activation event can be a user (e.g., John,Mary, or a user of the mobile device 125) hitting the “play” button ofthe music player.

In stage 315, the mobile device 125 has detected a content activationevent (e.g., the user hits the play button of the music player of themobile device 125). Thus, the mobile device 125 begins to activate thecontent (e.g., decoding the playing the audio file one by one).

FIG. 3 illustrates an example of progressively pre-loading contentrelated to an application according to the multi-conditional contentactivation criteria of the content. FIG. 4 illustrates an example inwhich the content server is configured to regressively remove someportion of the content from the mobile device according to themulti-conditional content activation criteria of the content.Specifically, the example in FIG. 4 is illustrated via three differentstages (stage 405, stage 410, and stage 415). As shown in the figure,mobile device 125 is communicatively coupled with content server 105 andcontent database 115. The content database 115 also stores the eightaudio files as described above. The content server 105 also includes themulti-conditional content activation criteria for the eight audio files.In addition to the four transmission rules enumerated above, the contentserver 105 also includes this additional rule: remove a portion of theaudio files when the corresponding condition is no longer satisfied.

Stage 405 is identical to stage 305 of FIG. 3. Specifically, the contentserver 105 has detected that the mobile device is located within thestudy room and that John is in also in the study room (e.g., based onfacial recognition data). Accordingly, the content server 105 instructsthe mobile device 125 to receive the first four audio files from thecontent database 115, as two of the four conditions within themulti-conditional content activation criteria are satisfied.

In stage 410, the content server 105 has detected that Mary is also inthe study room along with John. Accordingly, the content server 105instructs the mobile device 125 to receive the next two audio files fromthe content database 115, as three of the four conditions within themulti-conditional content activation criteria are satisfied.

In stage 415, however, after the next two audio files were received inthe mobile device 125, it is detected that Mary has left the study room.Thus, condition (3) is no longer satisfied. According to thetransmission rules, the content server 105 causes the two audio filesthat were received at the mobile device upon the satisfaction ofcondition (3) (i.e., the two audio files that were received in stage410) to be removed from the mobile device 125. The removal of theseaudio files frees up space within the mobile device 125 and alsoprovides better security of the content.

FIG. 5 illustrates another example of using the storage device topre-load (cache) content data via three stages (stage 505, stage 510,and stage 515) of the figure. As shown in FIG. 5, mobile device 125 iscommunicatively coupled with content server 105 and content database115. In this example, the content database 115 stores, among otherthings, object recognition data for ten different objects that arecommonly found in a grocery store. The object recognition data isactivatable, and it can be activated by an object recognitionapplication that is executed in the mobile device 125 to recognize (ordetect) the different objects within a grocery store. The content server105 also includes a rules database 220 (not shown) that includesmulti-conditional content activation criteria for content (e.g., theobject recognition data) related to the object recognition application.

The multi-conditional content activation criteria include the followingthree conditions: (1) a grocery store is within 50 meters of the mobiledevice; and (2) a grocery store is within 5 meters of the mobile device.In addition to the conditions, the multi-conditional content activationcriteria also specifies the following data transmission rules: (a)transmit one half of the content (e.g., object recognition data for fiveof the ten objects) when the first condition is satisfied; and (b)transmit the remaining content (e.g., object recognition data for theother five objects) when the second condition is satisfied. Preferably,mobile device 125 includes a location sensor and object recognitionsensor that is configured to recognize a grocery store and determine adistance between the grocery store from the mobile device (through imagerecognition, etc.). The mobile device 125 can also cooperate withexternal devices (e.g., RFID chip) that are placed near or inside thegrocery store to enable to mobile device 125 to determine its locationwith respect to the grocery store.

In stage 505, the content server 105 has detected that a grocery storeis within 50 meters from the mobile device (e.g., based on objectrecognition data for a grocery store). Accordingly, the content server105 instructs the mobile device 125 to receive object recognition datafor the first five objects from the content database 115, as the firstcondition within the multi-conditional content activation criteria issatisfied.

In stage 510, the content server 105 has detected that the grocery storeis within 5 meters from the mobile device 125. Accordingly, the contentserver 105 instructs the mobile device 125 to receive the objectrecognition data for the remaining objects from the content database115, as the second condition within the multi-conditional contentactivation criteria is satisfied. At this point, the object recognitiondata for all objects related to the grocery store has been transmittedto the mobile device 125. The object recognition data is stored in astorage area of the mobile device 125, but is not activated yet as thecontent activation event has not been detected. In this example, thecontent activation event can be a user launching (initiating) of theobject recognition application or the detection of the mobile devicelocated inside the grocery store.

In stage 515, the mobile device 125 has detected a content activationevent (e.g., the user initiating the object recognition application ofthe mobile device 125, detection of the mobile device 125 within thegrocery store, etc.). Thus, the content server 105 instructs the mobiledevice 125 to activate the content. Once activated, the objectrecognition application can begin using the downloaded objectrecognition data to recognize objects, present materials related to theobjects (e.g., promotion items, description, transaction data, etc.).

Yet another use case includes storing or caching content within medicaldevices. In such embodiments, patient data can be used to control themulti-conditional activation criteria. The conditions of the criteriacan operate as a function of the criticality of the patient's health forexample; perhaps based blood pressure data, pulse-ox data, heart ratedata, breathe rate data, or other factors. Patient records or otherpatient related information can be cached within the relative medicaldevices. For example, a doctor might have a tablet computer configuredto render a patient's data. As each progressive condition within thepatient data activation criteria is met, more of the patient data can bemigrated to the tablet. When the patient goes critical, or when the fullcriteria is met, the patient data can be activated and presented to thedoctor.
